Our environment and we

Environment is a place critically place around us,if we go through the dictionary meaning then it will include each and every thing which somehow related to our life. It can be living (biotic) or non-living (abiotic) things. It includes physicalchemical and other natural forces. Living things live in their environment. They constantly interact with it and adapt themselves to conditions in their environment. In the environment there are different interactions between animalsplantssoilwater, and other living and non-living things.

A person’s beliefs and actions depend on his environment. Modern people mostly think it is wrong to own slaves. But in Jefferson’s and Caesar’s environments slavery was normal. So, their actions did not look as wrong in their societies. Its simple definition is:

Interaction between human and environment in the past.

Although it is the surviving medium for all the organism ,but our need and greed have ruined it and pushing it to the dark line future

Below are the discussed aspects:-

Environmental pollution is one of the most serious global challenges. Wild-type organisms have a slower degradation rate of hazardous materials. Currently, advanced molecular biology tools along with conventional approaches allow us to rapidly degrade or accumulate hazardous materials from environments. This can help modify microorganisms to gain the ability to sense and degrade hazardous chemicals from contaminated sites, in turn, allowing us to grow vegetation and improve crop productivity. In this chapter, conventional and advanced molecular biology tools for the removal and detoxification of contaminants from soil and water to improve environmental conditions are highlighted.

1.Pollution Science

Environmental pollution is the unfavorable alteration of our surroundings, wholly or largely as a byproduct of man’s actions, through direct or indirect effects of the changes in the energy pattern, radiation levels, and chemical and physical constitution and abundance of organisms. Environmental pollution is a global problem and is common to both developed as well as developing countries, which attracts the attention of human beings for its severe long-term consequences. The decline in environmental quality as a consequence of pollution is evidenced by loss of vegetation, biological diversity, excessive amounts of harmful chemicals in the ambient atmosphere and in food grains, and growing risks of environmental accidents and threats to life support systems.

Depending on the nature of pollutants and also subsequent pollution of environmental components, the pollution may be categorized as follows:

1.Air Pollution

2.Water Pollution

3.Soil/Land Pollution

4.Noise Pollution

5.Radioactive Pollution

Pollution affect on human health

According to WHO

As the world gets hotter and more crowded, our engines continue to pump out dirty emissions, and half the world has no access to clean fuels or technologies (e.g. stoves, lamps), the very air we breathe is growing dangerously polluted: nine out of ten people now breathe polluted air, which kills 7 million people every year.

The health effects of air pollution are serious – one third of deaths from stroke, lung cancer and heart disease are due to air pollution. This is having an equivalent effect to that of smoking tobacco, and much higher than, say, the effects of eating too much salt.Facebook live: special talk on climate change with Arnold Schwarzenegger
Air pollution is hard to escape, no matter how rich an area you live in. It is all around us. Microscopic pollutants in the air can slip past our body’s defences, penetrating deep into our respiratory and circulatory system, damaging our lungs, heart and brain.

Air pollution is closely linked to climate change – the main driver of climate change is fossil fuel combustion which is also a major contributor to air pollution – and efforts to mitigate one can improve the other. This month, the UN Intergovernmental Panel on Climate Change warned that coal-fired electricity must end by 2050 if we are to limit global warming rises to 1.5C. If not, we may see a major climate crisis in just 20 years. 

Meeting the goals of the Paris Agreement to combat climate change could save about a million lives a year worldwide by 2050 through reductions in air pollution alone. The economic benefits from tackling air pollution are significant: in the 15 countries that emit the most greenhouse gas emissions, the health impacts of air pollution are estimated to cost more than 4% of their GDP. 

“The true cost of climate change is felt in our hospitals and in our lungs. The health burden of polluting energy sources is now so high, that moving to cleaner and more sustainable choices for energy supply, transport and food systems effectively pays for itself,” says Dr Maria Neira, WHO Director of Public Health, Environmental and Social Determinants of Health.

Air Pollution Effects

We release a variety of chemicals into the atmosphere when we burn the fossil fuels we use every day. We breathe air to live and what we breathe has a direct impact on our health.

  1. Breathing polluted air puts you at a higher risk for asthma and other respiratory diseases.
  2. When exposed to ground ozone for 6 to 7 hours, scientific evidence show that healthy people’s lung function decreased and they suffered from respiratory inflammation.
  3. Air pollutants are mostly carcinogens and living in a polluted area can put people at risk of Cancer.
  4. Coughing and wheezing are common symptoms observed on city folks.
  5. Damages the immune system, endocrine and reproductive systems.
  6. High levels of particle pollution have been associated with higher incidents of heart problems.
  7. The burning of fossil fuels and the release of carbon dioxide in the atmosphere are causing the Earth to become warmer. Read about the effects of Global Warming here.
  8. The toxic chemicals released into the air settle into plants and water sources. Animals eat the contaminated plants and drink the water. The poison then travels up the food chain – to us.

We live in an ecosystem where the action of one has the potential to affect the many. This can be a good or a bad thing, depending on what the action is. Our mistakes has polluted the environment that we live in and we are waking up and owning to the fact. We are trying to reverse the damage. The good news is that every positive action counts. The small effort you make towards a greener environment can start a healing ripple effect. We may still save what is left of our natural resources and make the world a better place to live in for our future
